2-{[(Pyridin-2-yl)amino]methyl}phenol

Acta Crystallographica Section E, 2012
The planes of the aromatic rings of the title compound, C12H12N2O, are twisted by 50.33 (15)°. The phenol O atom is a hydrogen-bond donor to the pyridine N atom, resulting in the formation of an eight-membered ring in the molecule. The

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

4-Hydroxy-1-oxo-1,2-dihydrophthalazine-6,7-dicarboxylic acid dihydrate

Acta Crystallographica Section E, 2008
In the crystal structure of the title compound, C10H6N2O6·2H2O, the OH and NH groups each serve as a hydrogen-bond donor to one acceptor site whereas the water molecules each serve as a hydrogen-bond donor to two acceptor sites. The hydrogen-bonding

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

NR4A1 Exerts Pro‐Tumor Role in Glioblastoma via Inducing xCT/GPX4‐Regulated Ferroptosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Purpose This study investigates NR4A1's paradoxical roles in glioblastoma (GBM) progression, focusing on its mechanistic link to ferroptosis regulation. We aimed to resolve conflicting reports of NR4A1 as both an oncogene and a tumor suppressor by defining its transcriptional control over xCT/GPX4‐mediated iron homeostasis and its clinical ...
